Add Spaces to the Required Modules List on Project Page

Spaces is a requirement with version 2.0 of this module. Please add this to the "Required Modules" section of the Views Gallery project page.

Side note: If Spaces is not installed, Views Gallery will upgrade from 1.x to 2.x and be functional, but will be deactivated if, at a later time, another module -- any module that is installed -- is deactivated. It's like Drupal realizes that a dependency is missing and turns Views Gallery off. I experienced this myself when I deactivated the AddToAny module (which is completely unrelated to Views Gallery or any of its dependencies).

Thanks! :)
